Colourful and deliciously warming, this salad has a beautiful balance of flavours across the potatoes, the salty Halloumi and the little bite of the radish and mustard. This dish is not only healthy, thanks to the vitamins, iron and potassium of the low-GI radish, but it also will look fantastic on any supper table. Adding a slice or two of ham turns this into a more substantial dish that will satisfy those carnivores among your friends and family!
